abstract

  • In this work pure CuCr2O4 and Mn-doped CuCr2O4 nanoparticles were prepared using Microwave combustion process. The phase analysis of the prepared samples is investigated using X-Ray Diffraction technique and an decrease in particle size observed from ...37 to ...26 nm with rise in Mn doping concentration. Further optical data revealed the presence of multiple Mn-related optical centres. Morphological studies revealed the prepared samples exhibited irregular plate-shaped agglomerates. Furthermore, the antibacterial performance of undoped CuCr2O4 and Mn-doped CuCr2O4 samples are investigated. At 500 °C, the electrical conductivity for the CuCr2O4 and Mn-doped CuCr2O4 samples were found to be 0.98 × 10 ...2 S/cm and 2.13 × 10 ...2 S/cm respectively. The activation energy of the pristine CuCr2O4 and Mn-doped CuCr2O4 samples was found to be 0.87 eV and 0.69 eV respectively.
